SPECIFICATION forming part of Letters Patent No. 7 14,830, datedDecember 2, 1902. Application filed October 17,1901. Serial No. 78,976.(No model.)

`To all whom t may concern.-

Beit known that I, JOHN A. STAPLES, a citizen of the United States,residingatNew burgh, in the county of Orange and State of New York,haveinvented certain new and useful Improvements in Clips for Springwork, ofwhich the following is a specification.

l My invention consists of an improvement in clips adaptedto be employedfor connecting together the constituent elements of springwork and isdesigned to produce a clip of the class described to be employed toconnect a wire spring to a brace-wir`e or a borderwire, rod, or ratan ofgreater diameter than the wire of the spring.

Clips have heretofore been produced and adapted for use where thespring-wire and the edge wire or the brace-wire are'of the samediameter; but it will be apparent that it is impracticable to employthat particular form of clip Where the edge Wire is of substantiallylarger diameter than the spring-wire. In my present invention I havemade such changes in the construction of clips as are necessary to applythe same toa spring-wire and an edge Wire or brace-wire ofradically-dierent diameters.

Referring to the accompanying sheet of p drawings, inwhich the samereference characters are used to designate identical parts in all thefigures, Figure l is a plan View of one corner of a bed or cushion,showing my improved clip employed in connecting the coil-springs to theedge rod or Wire. Fig. 2 is an inverted perspective View of the clip be-Fig. 3 is an inverted plan view showing the clip attached, and Fig. .Lis

a sectional view on the -line A A of Fig. 3.

In the drawings the reference-letter ct represents an edge wire, and theletter b a coilspring of any desired form and configuration.

`cured thereto.

In some classes of lspringwork the edge wire or rod a, is of severaltimes the diameter of the wire b of .the springwhich is to be se- Theclips c, which are to be assembled toconnect the rod and spring, havelabody portion d, whose interior area corresponds to the exterior size ofthe rod a to which it is to be attached. The body d is provided withsuitable connecting means in the form of an integral` wing or of two ormore ears e, which when the clip is. in place tion f, having its outeredge suitably shaped to lie against a portion of the Wire of the topstrand of the spring to which it `is to be attached., The part f isprovided With suitable means to engage the spring-wire, and when theparts are assembled these meansare bent over to partially embrace thewire b, as clearly shown in Figs. 3 and 4.

In some forms of construction of springwork the springs are curved orcomposed of spiral convolutions, and for such classes of work theattaching means of the ange f is preferably composed of a plurality ofears g, which are arranged on the edge of the flange, which is curved outhe arc of a circle corresponding in diameter to the diamet-er of thetop coil of the springs with which the clips are associated. In otherforms of construction of springwork springs are other than cirecular-as, for example, springs that are in tended to constitute orcompose the edge rows of springwork to make what is 'known as a springedge to the product are generally provided with square tops in order toprovide, among other things, a longer bearing on the edge wire. In suchforms the edges of the iianges f of the clips are made straight orsquare, in which case opposite edges are parallel with each other. Inthe latter construction the attaching means may be either the ears orlugs g or a single integral Wing. It is to be understood that the formof attaching means on either edge may be varied io suit theyrequirements of different :forms of springwork without departing frommy invention, the essential feature of which is the production of a clipadapted to be employed to attach constituent elements of springworkwhich are of unequal size or of different diameters.

With my improved construction of clip it will be apparent that theliange or horizontal portion `f is so located relative to the mainportion or body of the clip thatwhen the parts are assembled the wire ofthe spring b is brought directly against the center of the rod a., thusforming a brace, which Would not result if a iiat surface were given tothe clip, as in the previous forms of clips. Moreover,

ICO

with this construction when the parts are assembled the edge rod ctprojects an appreciable distance above the tops of the springs b,f

thus forming a border which serves to hold the upholstering in place, sothat it will not shift sidewise.

It Will of course be understood that my clips are adapted to be attachedto the interior brace rods or wires of springwork, as Well as to theedge wires and that the assemblage of these parts is made in the samemanner; also the edge wire or the wire composing the springs may becircular or Square in cross-section, and the associated portions of theclips will be formed accordingly. The drawing shows these elements as ofthe usual round wires, and the variations thereof here referred to aremerely in the form thereof.

. What I claim as new, and desire to secure by Letters Patent of theUnited States,'is-

l. A clip for springwork consisting of a curved body portion havingattaching means on one edge thereof and a horizontal portion on theother edge thereof, said horizontal portion provided with attachingmeans for the purposes described.

2. The combination with an edge rod at and a curved spring-wire b, of aclip connecting` them and consisting of the semicylindrical portion clprovided with attaching means on one edge thereof, a horizontal portionf on the other edge thereof'provided with ears g on the curved outeredge thereof.

3. A clip for springwork having a semicylindrical portion provided withattaching means on one edge, a flange on the opposite edge provided withattaching means, the latter attaching means being of less area than thesemicylindrical portion, whereby the clip is adapted to connect portionsof unequal size.

4. A clip for springwork having a curved body portion provided withattaching-ears on one edge, a iiange on the opposite edge arrangedapproximatelyon the line of the j unction of the ears and body portion,and attaching means on the edge of the iiange of less size than the earsto form a channel, where@ by the channel at the edge of the flange isapproximately opposite the center of the channel formed by the vbodyportion and ears.

In testimony whereof I affix my signature in the presence of twowitnesses.

JOHN A. STAPLES.
